Many people find a problem when dealing with liquid silicone products, which is that there are many silicone bubbles that cannot be completely removed, resulting in the product not being aesthetically pleasing and unable to achieve the expected effect, causing huge losses. Below, we will teach you how to reduce the bubbles generated after stirring liquid silicone gel. Let's learn together.
If it is a condensed liquid silicone product, less curing agent can be added and the operating time can be extended to achieve natural foaming effect.
When the amount of curing agent added is the same, the temperature of the operating space can be reduced, thereby prolonging the curing time and making it easier to remove bubbles.
During the process of stirring liquid silicone products, please try to stir in the same direction as much as possible to minimize the presence of bubbles.
4. Require manufacturers to reduce the viscosity of silicone during the production process, improve its flowability, and make it easier to release bubbles. However, if the viscosity is too low, adding more silicone oil will also deteriorate the performance of the product.
A more practical method is to use a silicone vacuum machine. No matter how viscous the liquid silicone product is, it can still be easily evacuated with a vacuum machine to remove all the bubbles inside.
